Product details
Overview
BCP5316TA from Diodes Incorporated is a PNP medium-power bipolar junction transistor in SOT223 package, rated for -80V VCEO, -1A continuous collector current, and 2W power dissipation. It features low saturation voltage (< -500 mV @ -500 mA), high DC current gain (100–250 at IC = -150 mA), and AEC-Q101 qualification for automotive reliability. It is used in medium-power switching and audio output stages.
For engineers reviewing the BCP5316TA datasheet, BCP5316TA pinout, BCP5316TA application, or BCP5316TA equivalent, key selection criteria include its -80V breakdown rating, gain group 16, thermal resistance (RθJA = 62°C/W), RoHS-compliant "Green" construction, and SOT223 surface-mount compatibility with standard PCB layout guidelines.
Technical Context
This PNP transistor operates in linear amplification and saturated switching modes, with verified DC current gain hFE of 100–250 at IC = -150 mA and VCE = -2 V. Its fT of 150 MHz supports moderate-frequency signal handling up to ~100 MHz under pulsed conditions.
The device uses a planar epitaxial die structure with low RθJL (19.4°C/W) and is characterized for operation across -65°C to +150°C. Its ESD robustness includes 4 kV HBM and 400 V MM ratings, meeting industrial and automotive stress requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -80 V - Maximum safe collector-emitter voltage before breakdown in common-emitter configuration. |
| IC (cont) | -1 A - Continuous collector current capacity; supports medium-power load switching without forced cooling. |
| PD | 2 W - Power dissipation limit on 50 mm × 50 mm 1 oz copper PCB; defines thermal design margin. |
| VCE(sat) | < -500 mV @ -500 mA / -50 mA - Low saturation voltage enables efficient switching with minimal conduction loss. |
| hFE (gain group 16) | 100–250 @ IC = -150 mA - Tight gain distribution ensures predictable biasing in amplifier and driver circuits. |
| fT | 150 MHz - Transition frequency confirms usable bandwidth for AF and low-RF signal amplification. |
| RθJA | 62 °C/W - Junction-to-ambient thermal resistance under standard mounting; informs heatsinking requirements. |
Pinout & Package
Package: SOT223 - Surface-mount plastic package with exposed collector tab for thermal conduction and mechanical anchoring. Dimensions per AP02002: D = 6.50 mm, E = 3.50 mm, E1 = 7.00 mm, L = 0.95 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | E | Current exit path; connected to higher potential in PNP operation; electrically isolated from tab. |
| 2 (Base) | B | Control terminal; requires negative base current relative to emitter to turn on device. |
| 3 (Collector) | C | Main current path; internally bonded to exposed metal tab for thermal and electrical connection. |
| 4 (Collector Tab) | C (common with Pin 3) | Thermal and electrical extension of collector; must be soldered to copper pour for thermal management. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP medium-power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCP5310TA | Lower hFE range (63–160); same VCEO, IC, and package. | Suitable where gain consistency is less critical; lower cost in non-precision bias designs. | Select when circuit tolerates wider hFE variation and does not require tight gain matching. |
| MJD2955G | TO-220 package; higher IC (-10 A), higher VCEO (-70 V), but larger footprint and no AEC-Q101 rating. | Used in high-current linear regulators or legacy industrial power supplies requiring through-hole mounting. | Choose only if board space allows TO-220 and automotive qualification is not required. |
Compared with BCP5310TA and MJD2955G, BCP5316TA offers superior gain consistency for precision biasing, AEC-Q101 compliance for automotive use, and SOT223 surface-mount efficiency-making it optimal for space-constrained, high-reliability medium-power switching.

FAQ
What is the maximum operating temperature for BCP5316TA?
The BCP5316TA has an operating junction temperature range of -65°C to +150°C, with storage temperature matching this span. Derating begins above +25°C ambient per the 62°C/W RθJA curve; at 70°C ambient, maximum continuous power drops to ~1.2 W on standard PCB mounting.
Is BCP5316TA pin-compatible with other BCP5x devices?
Yes-BCP5316TA shares identical SOT223 pinout (Emitter-Base-Collector-Tab) and mechanical footprint with all BCP51/52/53 variants, including BCP5310TA and BCP53TA. Electrical differences (e.g., VCEO, hFE) do not affect physical layout compatibility.
Does BCP5316TA require a heatsink in typical applications?
No external heatsink is required for continuous 1 A operation at ambient ≤50°C on a 50 mm × 50 mm 1 oz copper PCB, as confirmed by its 62°C/W RθJA and 2 W PD. Thermal performance improves significantly with larger copper pours or internal layers connected to the collector tab.
How does the gain group 16 affect circuit design?
Gain group 16 guarantees hFE between 100 and 250 at IC = -150 mA and VCE = -2 V, enabling precise base resistor calculation and stable quiescent point setting. This eliminates need for gain binning or trim resistors in production designs targeting consistent DC bias.
